Usually remembers to get the pointy end up
I used a Soller glass sleeve for the first time the other day, and had a couple issues maybe you guys could help with.
I followed the videos/info I've seen: put a couple CRs in the tube and inserted a dowel, put the sleeve on, fastened the ends. I mixed up epoxy (about the same weight as the sleeve), applied with a brush, and then used a credit card to squeegee all the excess resin out after the glass and tube were thoroughly wetted. Put a heatshrink sleeve on, and use the heat gun.
My issues:
1) I was led to believe there would not be any longitudinal shrinkage in the heatshrink (<1%), but I actually got >10%, so the wrap shrunk up more than I allowed for, and I was left with an inch or two on each end that didn't get wrapped. Is this typical (the shrinkage)? Do you guys normally do something to fasten down the ends of the heatshrink?
2) After removing the heatshrink, the glass weave texture is still visible on the surface. Did I squeegee too much epoxy off? How do I know how much epoxy to leave in, to get a glass-smooth finish after the heatshrink, but not too much excess weight?
Thanks,
Kelly
